- Scandium is a
chemical element that has the symbol Sc and atomic number 21.
- A silvery white
metal that is always present as compounds, scandium ores occur as rare
minerals from Scandinavia and elsewhere.
- It is sometimes
considered along with yttrium, and the lanthanides and actinides, to be
a rare earth element.
- Scandium is a rare,
hard, silvery, rough very dark metallic element that develops a slightly
yellowish or pinkish cast when exposed to air.
- Scandium is
distributed sparsely on earth, occurring only as trace quantities in
many minerals. Scandium is more common in the sun and certain stars than
on Earth.
- The extraction of
Sc(III) proceeds according to the cation-exchange reaction at lower
acidity and to a solvating reaction at higher acidity.
- The quantitative
extraction for Sc(III) with PC-88A was found within 1 min while with
D2EHPA the same was attained only after 5 mins of shaking, though 77.6 %
Sc(III) was extracted into the organic phase within 1 min.
- Separation of
Sc(III) was also carried out from some commonly associated metals and
the method further extended for its recovery from synthetic and real
solutions of Fe(III), Al(III) and Mg(II) scrap.
- The main application
of scandium by weight is in aluminium-scandium alloys for minor
aerospace industry components, and for unusual designs sports equipment
(bikes, baseball bats, firearms, etc.) which rely on high performance
materials.
- It is used in
lacrosse sticks; a light yet strong metal is needed for precise
accuracy, speed and its useful in the making of aircraft and spacecraft
structures, probably alloyed with other metals.
- Scandium (45Sc) NMR
was used to explore the B-site order-disorder in the Perovskite
piezoelectric material.
- Scandium can
significantly increase strength and reduce grain size and has been added
to aluminum alloys in the former soviet union for missiles and MIG
fighter applications.
- The two-stage
amorphization found in the present case of scandium molybdate is in
contrast to the single-stage amorphization reported in other
isostructural Sc2(WO4)3 and Lu2(WO4)3 occurring at 4 and 5 GPa,
respectively.
